In my case, I have a Modified RS2 turbo that blew so much air that the sport
quattro valve did not prevent IC blowout....  hmmmmm, cool....  Definitely
worth a retry, I'll prolly go with the larger HKS electro-mechanical unit

 Well the turbo put out that 15 psi, so it's a wash....  The turbulence
created shoving pressured air back into the turbo prolly offsets any
"pressure spin" anyhow....  The whole theory behind the reroute is noise,
freewheeling the turbo, and what I call "measured air" theory....  Not as
critical in the 86-89.5 cars (with decel valve), but the mass air cars make
paying attention to this pretty key......
